If other games can have their threads, why not this? :V
Everyone plays TF2. And if somebody doesn't, sooner or later they will :V
To start it off before it goes somewhere: Which classes do you play the most and with which setup?
For me, probably Sniper with Huntsman/Jarate.
Huntsman is simply more fun than the rifle(and kills look cooler too, plus you aren't that distance camper which doesn't get any action :V
Jarate over Razorback simply because it's Team Fortress.
Plus you should learn how to spycheck and Ambassador doesn't give a fuck anyways :V
Second probably Pyro... Normal flamethrower(compression blast is fun, bonus cool points for deflect kills, light arrows on fire, put out fires), Axtinguisher. It's always cool to take out a demoman with targe+eyelander.
